Dear all,

here's another one from Lake Schmiechen (SW Germany). Could it be Culex pipiens?

Thanks,
Martin

Superficially it looks OK for Cx. pipiens, but there seems to be an indication of white rings on the tarsi; and the pale bands on the abdominal tergites are very even. As a rule the bands expand along the lateral margin in pipiens. So I'm left wondering whether this might be a Culiseta species, such as morsitans. Fortunately Culiseta have a good character to check - they possess prespiracular setae, which Culex don't have.

Thanks Tony, much appreciated!
I will check the setae tomorrow, Monday, when I have access to a binocular microscope.

OK, under the microscope it looks like it does have prespiracular setae (and no postspiracular setae).
